二维及彩色多普勒超声诊断桥本甲状腺炎合并甲状腺结节

目的:评价二维及彩色多普勒超声对桥本甲状腺炎(HT)合并甲状腺结节的诊断价值。方法:对48例确诊为HT并伴发结节的患者行超声检查,记录甲状腺及其伴发结节的超声影像学特征。结果:40例甲状腺体积呈不同程度增大,8例甲状腺体积未见增大;35例甲状腺内部弥漫性回声减低,7例回声改变不明显,或内部回声基本正常,6例局部回声增粗减低;单个结节15例,10例为HT结节,3例为乳头状癌,2例为滤泡性腺瘤。多个结节33例,其中4例合并乳头状癌,4例合并滤泡性腺瘤,5例合并结节性甲状腺肿;彩色多普勒超声检查显示甲状腺内血流丰富者5例,血流稀少者5例,余病例未见明显变化。结论:二维及彩色多普勒超声对于HT合并结节的诊断及鉴别诊断具有较高的实用价值。

Two-dimensional and color doppler ultrasonographic in diagnosis of Hashimoto thyroiditis with nodular lesions

Objective To assess the value of two dimensional and color doppler ultrasonography in diagnosis of Hashimoto thyroiditis(HT) with nodular lesions.Method 48 cases of HT with nodular lesions were analyzed about the ultrasonographic image characteristics.Results The volume of thyroid increased in 40 cases with different degrees.Single nodule appeared in 15 cases,among which 3 cases were papillary carcinoma,2 cases were follicular adenoma.Multiple nodules were in 33 cases among which 4 cases were papillary carcinoma,3 cases were with follicular adenoma and 5 cases were with nodular goiter.Color doppler flow imaging showed that blood flow obviously increased in 5 cases,decreased in 5 cases,and normal blood flow in other cases.Conclusion Ultrasonography has high value in diagnosis and differential diagnosis of HT with nodular lesions.
